European Space Agency uses Yokogawa instruments to achieve precise laser tuning for satellites
03 August 2022
The European Space Agency (ESA) is using the precision of Yokogawa’s optical wavelength meters to ensure accurate tuning of lasers used in Earth-to-space communications.
ESA operates a network of geostationary satellites known as the European Data Relay System (EDRS). These satellites communicate with a constellation of European low Earth orbit (LEO) satellites called Sentinels, which are used for Earth monitoring applications.
The EDRS satellites use radio communication to upload the LEO satellites’ images and other data to terrestrial servers.
The challenge is that the growing amount of information from LEO and geostationary satellites, and from satellite constellations, will mean that the available bandwidth from radio communication links will soon be too low to meet ESA’s data transfer needs.
